Hey, thanks for taking time to break this down. So essentially, what I have to do is get values from a PC or a serial monitor to the arduino through the serial port, values like acceleration and throttle etc. These values are sent from the arduino to the futaba t14sg, which will be connected to some car and control its acceleration etc. I do know I will have to use the trainer port, but I was unclear about that. Essentially, the futaba is more like a transmitter with arduino relaying the values.
